I have the black Avias from KickMax in a size 6 1/2 and I found the toebox to be VERY roomy. Next time I would order a half size smaller.
Everyone's foot is different though. I have been thinking of trying Rykas which some people have said run true to size, and when I went to the mall to try them on, I found that I would need a size 7 in them.
Sorry to add to the confusion,
Tammy
